Chapter 8.1, Problem 2TY

A survey indicates that the mean annual wages for forensic science technicians working for local and state governments are $60,680 and $59,430, respectively. The survey includes a randomly selected sample of size 100 from each government branch. Assume that the population standard deviations are $6200 (local) and $5575 (state). The two samples are independent. At α = 0.10, is there enough evidence to conclude that there is a difference in the mean annual wages? (Adapted from U.S. Bureau of Labor Statistics)
